PHYSICAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Explosives Not applicable - - - - Containing no chemical groups with explosive properties
2 Flammable gases (including chemically unstable gases) Not applicable - - - - Classified as "solid" according to GHS definition
3 Aerosols Not applicable - - - - Not aerosol products
4 Oxidizing gases Not applicable - - - - Classified as "solid" according to GHS definition
5 Gases under pressure Not applicable - - - - Classified as "solid" according to GHS definition
6 Flammable liquids Not applicable - - - - Classified as "solid" according to GHS definition
7 Flammable solids Not classified - - - - Considered non-flammable because tellurium, which can be produced by burning tellurium (Te) in air, is a stable oxide existing in nature as a mineral (Chemical Dictionary, 1994).
8 Self-reactive substances and mixtures Not applicable - - - - Containing no chemical groups with explosive or self-reactive properties
9 Pyrophoric liquids Not applicable - - - - Classified as "solid" according to GHS definition
10 Pyrophoric solids Not classified - - - - Considered non-flammable because tellurium, which can be produced by burning tellurium (Te) in air, is a stable oxide existing in nature as a mineral (Chemical Dictionary, 1994).
11 Self-heating substances and mixtures Not classified - - - - Tellurium oxide is considered non-flammable because it is obtained by burning tellurium (Te) in air and it is a stable oxide occurring in nature as a mineral (tellurite) (Chemical Dictionary, 1994).
12 Substances and mixtures which, in contact with water, emit flammable gases Not classified - - - - Stable to water (insoluble, Lide (84th, 2003))
13 Oxidizing liquids Not applicable - - - - Classified as "solid" according to GHS definition
14 Oxidizing solids Classification not possible - - - - Classification not possible due to lack of data, though being inorganic compounds containing oxygen
15 Organic peroxides Not applicable - - - - Not organic compounds
16 Corrosive to metals Classification not possible - - - - Test methods applicable to solid substances are not available

HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Not classified - - - - Based on the rat LD50 (oral route) value of >5,000mg/kg (RTECS (2004)).
1 Acute toxicity (Dermal) Classification not possible - - - - No data available
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Due to the fact that the substance is "solid" according to the GHS definition and inhalation of its gas is not expected.
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - - No data available
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - No data available
2 Skin corrosion/irritation Classification not possible - - - - No data available
3 Serious eye damage/eye irritation Classification not possible - - - - No data available
4 Respiratory sensitization Classification not possible - - - - No data available
4 Skin sensitization Classification not possible - - - - No data available
5 Germ cell mutagenicity Classification not possible - - - - No data available
6 Carcinogenicity Classification not possible - - - - No data available
7 Reproductive toxicity Category 2 Warning H361: Suspected of damaging fertility or the unborn child P308+P313: IF exposed or concerned: Get medical advice/attention.
P201: Obtain special instructions before use.
P202: Do not handle until all safety precautions have been read and understood.
P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ...
Based on the evidence of adverse effects on pup development (malformation and fetal death), described in RTECS (2006) (though no data are available regarding parental toxicity).
8 Specific target organ toxicity - Single exposure Classification not possible - - - - Insufficient data available. Refer to "Tellurium" (ID_0236, CAS_13494-80-9).
9 Specific target organ toxicity - Repeated exposure Category 2 (nervous system) Warning H373: May cause damage to organs through prolonged or repeated exposure (nervous system) P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P314: Get medical advice/attention if you feel unwell.
P501: Dispose of contents/container to ...
Based on the evidence from animal studies including "effects on the parasympathetic nervous system, muscle contraction/twitching" (RTECS (2004)). The effects on experimental animals were observed at dosing levels within the guidance value ranges for Category 2. Refer to "Tellurium" (ID_0236, CAS_13494-80-9).
10 Aspiration hazard Classification not possible - - - - No data available

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Not classified - - - - Since it was suggested that relevant toxicity is not indicated in the water solubility (6.7mg/L(Merck 13th, 2001)) of this substance, according to from 96-hour LC50>1000000microg/L of the fish (Fundulus Heteroclitus) (AQUIRE (2003)), it was classified into Not classified.
11 Hazardous to the aquatic environment (Long-term) Category 4 - - H413: May cause long lasting harmful effects to aquatic life P273: Avoid release to the environment.
P501: Dispose of contents/container to ...
Since although acute toxicity is not reported within the aqueous solubility concentrations, it was a metallic compound, and the underwater action was unknown, it was classified into Category 4.
